Need help identifying this muzzle brake

I just recently purchased this gun and I need some help identifying this muzzlebrake and I am also wondering your thoughts on it. Does it looklike it would be good or bad? What to look for in a good muzzle brake? http://www.gunbroker.com/Auction/Vie...Item=218104325

I have heard the baffle type are more efficient, but a friend has a similar brake to yours on his 300RUM and it is nice to shoot. The only thing wrong with those style brakes is when shooting prone they kick up dust/twigs/leaves, etc. It will work well though, or should at least. I'm sorry I can't identify it for you.
